On Foo Fighters' tour closer in Australia last night (January 30), the Weezer leader joined Dave Grohl and co. for the cover, with Cuomo lending both guitar and vocals onstage in Melbourne. Weezer themselves also provided the show's opening set.

Since this is 2018 and all, someone of course pulled out their phone and captured the cover of "Detroit Rock City," which you can watch for yourself below. Foo Fighters also apparently took on AC/DC's "Let There Be Rock" at the show.

Watch the fan-captured cover of "Detroit Rock City" below, where you'll find Weezer's tweet about the collision of worlds.
